正常结肠黏膜与腺瘤性息肉比较


左侧为正常结肠黏膜,右侧为腺瘤性息肉(管状腺瘤)。腺体不规则,并有深染的、密集的细胞核 。肿块是良性的,分化很好的,与正常结肠组织相似。
A microscopic comparison of normal colonic mucosa on the left and that of an adenomatous polyp (tubular adenoma) on the right is seen here. The neoplastic glands are more irregular with darker (hyperchromatic) and more crowded nuclei. This neoplasm is benign and well-differentiated, as it still closely resembles the normal colonic structure.
